Abstract

L'invention concerne un procédé et un appareil de coordination de canal. Le procédé est utilisé pour un premier point d'accès (AP), le premier AP étant un AP desservant actuellement un terminal. Le procédé consiste : lorsqu'il est déterminé qu'un canal doit être configuré pour un service en temps réel lancé par le terminal, à détecter un second AP qui nécessite une coordination de canal ; à envoyer une signalisation de demande de coordination de canal au second AP, la signalisation de demande de coordination de canal comprenant un canal désigné que le premier AP demande de coordonner ; et lors de la réception d'une première signalisation de rétroaction de coordination de canal, utilisée pour indiquer d'accepter de coordonner le canal désigné, envoyé par le second AP, à déterminer, en fonction de la première signalisation de rétroaction de coordination de canal, que le second AP accepte de coordonner le canal désigné. Ainsi, selon la présente invention, un terminal peut être configuré en fonction d'un canal ayant été coordonné avec un second AP, ce qui réduit l'interférence d'un réseau sans fil par l'intermédiaire d'une coordination de canal entre différents AP, et améliore également la stabilité du canal configuré pour le terminal.
